Nelson, Oakland, Calif., assignors to Qalifornia I Gotten Mills Company,Oakland, Calif. Application November 29, 19 12. seiial No. 512,286ZGlaims. (01.15 229) f This invention relates to a roorers moi: of thetype used for applyineand for spreading not tar on roofs.

Heret'ofore mops of this type have been produced, the structure of thediiferent mops being similar in'certain respects, such as in theemployrnent of a straight Wooden stick that serves "as a handle and as asupport for the mop head. A metal tube is ordinarily secured to theouter end of the mop stick and the mop head that is of cotton cords oryarn is secured to a projecting end of the tube. The purpose of the tubeis to prevent burning or charring of the outer end of the mop stick bythe hot tar when the amp head is dipped into such tar. In most of theseprior structures the mop yarn is secured by a wire to the metal tube,and not to the stick. Considerable diflic'ulty is encountered in tightlysecuring the yarn to the tube, particularly where the mop headisrelatively large. Also the tubes must be perforated for the v'virswiththe result that the hot tar gets between the mop head and the stick andthe Stick is not only charrd'or burned, but

this tar makes it difficult to remove the map- 'head-seenring Wire forreplacing a mop head.

jAttem'ptsto overcome theseobjectiohs have res'ult'e'd in making upspecial mop heads provided with a metal eye or hook for engagement. Witha hook secured to the end of the amp stick. A

ihetals'leeve reciprocahle on the mop stickis then forced against themop head to hold the latter rigidand to prevent burning Of the end Ofthe stick. These attempts have been fairly satisfactor'y, but haveprecluded the individual operator from making up his own mop head fromcohveritional lengths of yarn to suit himself. Also the conventionalstructures have not entirely stopped burning of the stick and do notprovide the strength desired, or the economy in manufac- 'ture that isa'quite' important consideration.'

The principal object of this invention is to provide a structure thatovercomes the above mentioned objectiohs, and which mop is very easilymanipulated for replacing the mop head. Also there is'no need in mystructure for providing specially made up mop heads with eyes or hookssecured thereto, or for tightening or bending wires in order to securethe mop head in place for use. Another object of my invention is theprovision of a mop that is economical to make and to use. The economicaluse resides in the fact that the only part-that requires replacement inuse is the mop yarn. There are'no wires, metal bands, or thelike,- thatrequire replacement.

Fig. 3 is a sectional view take'hbh line 3" 3 of Fig.2. v V j In detail,the map stick I, which is of World and straight, is provided with acylindrical; tubular sleeve 2 t an ifecipfocable oh the oiiter endportior'i thereof. Sleeve 2 is of metal and is adapted to fit the Stiek1 rather til'b'sely, but not so close as to prevent relatively easysliding of the tube on the stick. The endof the stick oppdsite saidouter end ortion thereof is eitposedahdprovidesahanme for holding By theoperat r. Ordinarily this ei'iposedpiirtioh of the stick may befrom'ahout tv'vo tdthree times the meteor tube 2 or stem three feet;ambush it be lon er or shorter seeming us the reunitemerits of the jobto be dohe. r

The niop head ispref ably refilled-iron lengths" of conventional fhOpyarn, such as iiitlie io'rf'r'i, 6f cotton core, string, em; and tvh'ihleh'gths'a're' secured to the stick by in or a apbeai u shapea holder orremove? heavy pring tviie providin legs 3 and a 'cl'ci'se'd end portion4 The portions or said" legs "at their free ends are" bent toward eachother for" forming laterally extenuing projections 5 J The outer "endliqrtioh of the stick lis formed on two of its opposite sides with apair f 'greoves outer end oi the stick. i N

The legs 3 or theinop-hea noiaerar pf form length and ear lhgth 1'11that the end portion 4 of theh'cilde'r' 'will (as: end transverse y ofhole'l that are nearest the outer end of-the mop stick. For a light mophead, the projections 5 may be in the hole I most remote from the outerend of the handle. For a medium mop head, the said projections may be inthe hole I that is between the above mentioned holes.

It is thus seen that the operator may make up a mop head to suit hisdesires, using similar lengths of mop yarn, or a combination ofdifferent lengths, and any desired amount of yarn.

The wire mop head holder is preferably formed so that the legs 3thereofwill tend to spring apart as indicated at III in Fig. l in dot-dashlines, unless held substantially parallel in grooves B. Thisfacilitatesthe replacement of burned or worn out mop heads.

, In securing the holder and a mop head thereonto the stick I, the legs3 of the holder are placed in grooves 6 with projections 5 on said legs.in the recesses or hole I that will bring the head nearest to the outerend' of stick 7 I. The tube .2 is slipped toward the handle portion ofstick I so as to unc yer the grooves and holes I inprder to makethisoperation possible. After the legs'3 are in grooves B as aboveexplained, the sleeve 2 is moved axially of stick I toward the mop headfuntil 'theile'gs 3 are enclosed therein, thus holding said legsfin thegrooves B and also holding ,it'he projections 5 in the desired hole I,

I 'The outer end of sleeve 2 is preferably bell- ,shap'ed as indicatedat II, so that the yarn that q o iex'tends betweemthe outer end of stickI and 'the end portion [of the holder will be enclosed .therein,Thefree, annular edge of the bell shaped .part IIwill verytightlyengage'the yarn and im anent: the yarn within said bell-shaped 'par'twill be so compacted as to preclude'the hot itarin whichthe mop head isdipped from passing a) stick I; When the bell-shaped part I of thesleeve encloses that portion of the mop il'ie'ad above described theouter end of stick I is within the sleeve 2 and as the sides of saidsleeve "andsaid part II thereof are imperforate, it is 'seen'that no hottar can reach the outer end of the stick I to char or burn the latter.When the sleeve 2 is retracted from the mop head to release. the legs 3,the bell-shaped part II will, of course, move with the sleeve to theposition I2 indicated in dot-dash line in Fig. 1. U In order to. securethe sleeve 2 and its bellshaped end II in the operative position shownin .liig. l, the sleeve ispreferably formed with a slot I3 extendinglongitudinally thereof from the .end edge of the sleeve that is remotefrom the :mophead. This slot extends toward the part II only a smalldistance sufiicient to enable drawing Y the edges of the slot at the endedge of the tube toward each other'a suflicient distance to enable atight gripping "of the stick by the tube adjacent "its said endedge.Opposed ears llrigid with 'said sleeve are provided at opposite sides ofsaid slot I3 at the open end of the latter, and a screw ,I5may extendthrough an aperture in one of said le ars" into threaded engagement witha threaded f laperture the other ear for drawing the edges of the slottoward each other and consequent pping of the stick.

The tube 2 with its bell-shaped end II, when in the position indicatedin Fig. 1, functions to hold the mop head rigid relative to the stick Iand centered on the axis of the latter. Also the stick is thoroughlyprotected from the hot tar into which the head may be dipped, eventhough the mop is dipped into the tar so far that the tar covers thebell-shaped part II and part of the sleeve 2,

The replacement of a burned or worn out mop head merely requiresloosening screw and slipping'of the tube 2 and part II on stick I untilI .said part II reaches position I2. The holder and mop head thenautomatically will fall from the stick. As legs 3 of the holder springapart when released, the old mop head is easily cut from the holder, orslipped off the latter and a new head can be readily placed on theholder. In some instances several holders are made up by an operator inadvance to enable quick replacement of a mop head without waiting forthe old one to cool, and in other instances the operator may havedifferent sizes of mop heads made up for work in difierent places one.job. The changing from one mop head to another is very easy and quicklydone by virtue of the structure herein described.

The extreme rigidity and tightness with which the 'mop head can be heldby the sleeve 2 and its part II is largely dependent upon the capacityof the wire holder to hold onto the mop stick when the part II of sleeve2 is forced against the mop head. The degree to which the said part canbe forced against the mop head determines the effectiveness of the sealthat the compacted yarn provides in the part I I for preventing passageof hot tar to the handle. By applicant's structure, it will be seen thatwhere the wire of the mop head holder is fairly heavy, as is the casehere, the part II can be driven against the mop head with great forcewithout loosening the hold of theholder on the stick. Thus no delicacyneed be observed by the operator in tightening the sleeve and part IIagainst the mop head, and a tight seal can be insured always, as well asa rigid mop head.
